The primary reason for rapid continuous rewarming of the area affected by frostbite is to:
A. Lessen the amount of cellular damage
B. Prevent the formation of blisters
C. Promote movement
D. Prevent pain and discomfort
Correct Answer: A. Lessen the amount of cellular damage
Rapid continuous rewarming of frostbite primarily lessens cellular damage. Rapid rewarming is the single most effective therapy for frostbite. Heat conduction and radiation from deeper tissue circulation prevent freezing and ice crystallization until the skin temperature drops below 0°C.
Option B: Blisters contain high amounts of thromboxane and prostaglandins. They contract and dry within 2-3 weeks, forming a dark eschar that sloughs off in 4 weeks.
Option C: Before movement can be improved, the cell injury should be resolved first.
Option D: It does not prevent the formation of blisters. It does promote movement, but this is not the primary reason for rapid rewarming. It might increase pain for a short period of time as the feeling comes back into the extremity.
